1. A method comprising:
- receiving mobile device data over a period of time from a plurality of mobile devices associated with a length of road comprising a plurality of subsections of road;
calculating, by at least one processor, from the mobile device data, a number of mobile device readings per subsection of the length of road and a difference between traffic flow of a first subsection and a second subsection of the length of road;
determining whether the number of mobile device readings for the first subsection is above a probe quantity threshold;
determining whether the number of mobile device readings for the second subsection is above the probe quantity threshold;
determining whether the difference between traffic flow of the first subsection and the second subsection of the length of road is above a variance threshold;
in response to the number of mobile device readings for the first subsection being above the probe quantity threshold, the number of mobile device readings for the second subsection being above the probe quantity threshold, and the difference between traffic flow of the first subsection and the second subsection of the length of road being above the variance threshold, indicating a different traffic flow level for the first subsection of the length of road than the second subsection of the length of road; and
in response to the number of mobile device readings for the first subsection being above the probe quantity threshold, the number of mobile device readings for the second subsection being above the probe quantity threshold, and the difference between traffic flow of the first subsection and the second subsection of the length of road being above the variance threshold, merging the first subsection and the second subsection into composite section, wherein subsequent traffic determinations are calculated for the composite section rather than the first subsection and the second subsection.

Abstract
Precision traffic flow indication may involve receiving device data over a period of time representing a plurality traffic flow readings associated with a road involving a plurality of subsections. Calculating traffic flows and determining road subsections having similar traffic flows may also be involved. Also, indicating a different traffic flow level for a first subsection and a second subsection of road may be involved.
